TUBULAR BOOSTER Russian patent published in 2003 - IPC

FIELD: mechanical engineering, in particular, propulsion units for rapid propelling of rigid bodies. SUBSTANCE: the propulsion unit is positioned in combustion chambers formed by interchamber partitions and made for changing of their volume. The combustion chambers are connected an electric circuit. The means for initiation is made in the form of electric primers installed in the propellant charge. The combustion chamber closest to the outlet from the body is designed for dynamic locking of the latter and is provided with a locking partition. EFFECT: enhanced mass of the propelled body and the range of its flight. 3 cl, 3 dwg
